: Modified packages created by the homebrew community to run on modified consoles without official digital signatures. The Core Requirement: Jailbreakable Firmware
Use an ExFAT-formatted USB drive. PKG files must be placed in the root of the drive (not inside folders) for the PS4 to detect them. The Installation Process: Plug the USB into the PS4. Navigate to Settings > GoldHEN or Debug Settings . Select Package Installer .
